1. SAFETY TERMS AND SYMBOLS
Please take a moment to review these safety terms and symbols which may appear in this manual or on Equipment to prevent damage to the Function Generators.
Measurement category I is for measurements performed on circuits not directly connected to MAINS.
Measurement category II is for measurements performed on circuits directly connected to the low voltage installation.
Measurement category III is for measurements performed in the building installation.
Measurement category IV is for measurements performed at the source of the low-voltage installation.
WARNING. Warning statements identify condition or practices that could result in injury or loss of life.
CAUTION. Caution statements identify conditions or
practices that could result in damage to this product or other property.

NOTE: This lead/appliance must only be wired by
competent persons
WARNING: THIS APPLIANCE MUST BE EARTHED
IMPORTANT: The wires in this lead are coloured in
accordance with the following code:
Green/ Yellow: Earth
Blue: Neutral
Brown: Live(Phase)
As the colours of the wires in main leads may not correspond with the colours marking identified in your plug/appliance, proceed as follows:
The wire which is coloured Green & Yellow must be connected to the Earth terminal marked with the letter E or by
the earth symbol 
or coloured Green or Green & Yellow.
FUNCTION GENERATOR
USER MANUAL
The wire which is coloured Blue must be connected to the
terminal which is marked with the letter N or coloured Blue or Black.
The wire which is coloured Brown must be connected to the terminal marked with the letter L or P or coloured Brown or Red.
If in doubt, consult the instructions provided with the equipment or contact the supplier.
This cable/appliance should be protected by a suitably rated and approved HBC mains fuse: refer to the rating information on the equipment and/or user instructions for details. As a guide, cable of 0.75mm² should be protected by a 3A or 5A fuse. Larger conductors would normally require 13A types, depending on the connection method used.
Any moulded mains connector that requires removal /replacement must be destroyed by removal of any fuse & fuse carrier and disposed of immediately, as a plug with bared wires is hazardous if a engaged in live socket. Any rewiring must be carried out in accordance with the information detailed on this label.

2. INTRODUCTION
The GFG-8210A Function Generator is a stable low distortion instrument which generate signals in the frequency range up to 10MHz. Typical applications include a wide range of audio response testing applications, vibration testing, servo system evaluation, ultra sound applications, and etc.
The instrument includes the following features: logarithmic and linear sweep capabilities, together with a built in frequency counter. The sweep capability simplifies the task of finding resonant points of speakers, filter networks and other networks structures. An oscilloscope may be connected to this instrument for the response to be displayed. The counter can be switched to measure and display the frequency of an external signal up to 150MHz.
zADDITIONAL FEATURES
1.Low distortion waveforms (sine, triangular and square).
2.Signal output in eight decade stages, 0.1Hz to 10MHz.
3.Adjustable sweep time and sweep width both in linear and logarithmic modes.
4.Duty cycle control with signal inversion capability.
5.External Voltage controlled Frequency (VCF).
6.A second output for TTL or adjustable CMOS pulses.
7.50 ohm main signal output with DC offset adjustment and 20dB attenuation capability.
8.Supplied with two BNC test leads and AC power cord set.
